Sign PDF
Sign PDF visually adds a signature image to a chosen page of one PDF entirely inside the browser.
The PDF and signature stay on this device and are processed only in a dedicated browser worker.
This visually adds a signature image to the PDF. It is not a legally qualified electronic signature (no eIDAS-qualified signing, identity verification, certificate, or audit trail), and it is not a multi-party signing workflow.
Limits: one PDF up to 25 MB, 200 pages, and 75 MB output. Signature image up to 5 MB. Encrypted or password-protected PDFs are rejected.
How to use it
- Select one PDF from your device and wait for its page count.
- Draw a signature by hand, or upload a PNG or JPEG signature image.
- Choose the page, then adjust its position and size on that page.
- Download the signed PDF once the dedicated browser worker finishes.
Draw a signature by hand with a mouse or touchscreen, or upload an existing PNG or JPEG signature image, then position and size it on the selected page before starting. A dedicated browser worker embeds the signature onto the page without altering its dimensions. This is not a legally qualified electronic signature: there is no eIDAS-qualified signing, identity verification, certificate, or audit trail, and it does not support multi-party signing workflows. Files are not uploaded to Tooliba, retained after the session, or included in analytics. The source PDF may be at most 25 MB and 200 pages, the signature image up to 5 MB, and generated output is limited to 75 MB. Password-protected or encrypted documents are rejected rather than decrypted.
